2. Structure Characteristics and Working Principle
2.1 Working Principle
The large amount of air created by centrifugal blower will directly blow to the
models of IMM after being moisture absorbed by rotator honeycomb to form
drying air with low dew-point. And then air discharges through air outlet of mold
closing chamber and returns to mold sweat dehumidifier through return air pipe.
In this way, a circle finished.
The air around mould is very dry with dew-point less than or equal to 5 ℃ .
Environmental temperature drops fast during the mould rapid-cooling, but temp.
would not fall to 5℃. Therefore, dewdrop would not come into being during
mould rapid-cooling.
